Abstract (in Japanese) (See Japanese page) 
(in English) This paper proposes a low-radiation loss on-chip antenna using sapphire substrate for implantable medical device. An on-chip antenna using a silicon substrate has a radiation loss due to absorption by low-resistivity silicon substrate. The proposed on-chip antenna was fabricated on a sapphire substrate to improve antenna gain. The fabricated on-chip antenna has a small size of 5.0 mm × 5.0 mm and the maximum return loss is -3.58 dB at the center frequency of 360 MHz. The maximum gain of the fabricated antenna is -29.2 dBi and it's confirmed that the on-chip antenna using a sapphire substrate achieves 12.9-dB higher gain compared with a silicon substrate. This improvement means that the implemented on-chip antenna can reduce a power consumption of transmitter chip by 95 % compared with that on a silicon substrate. Further, the transmitter using the fabricated antenna and a transmitter chip succeeded signal transmission at the distance of 10 cm. Therefore, the fabricated antenna is suitable for a data transmission antenna in implantable wireless medical systems.
